Results for tag: "Image Guided Radiotherapy"

Image-Guided Radiotherapy (IGRT) is a method of radiation therapy that employs imaging techniques to deliver precise doses of radiation to cancerous tissues while minimizing exposure to surrounding healthy tissues. Within the context of Nuclear Medicine and Radiopharmacology, which are concerned with the use of radioactive substances in diagnosis and treatment, IGRT stands out as a complement rather than a direct component. Nuclear Medicine involves using radiotracers or radiopharmaceuticals to visualize and treat diseases, with applications such as Positron Emission Tomography (PET) and Single-Photon Emission Computed Tomography (SPECT) aiding in disease diagnosis and therapy planning. Radiopharmacology deals with the drugs used in diagnosis and therapy that involve radioactivity. IGRT, while not directly utilizing radiopharmaceuticals for treatment, benefits from the precise diagnostic information that nuclear medicine provides. This synergy helps clinicians to better target radiation doses for cancer treatment, adjusting for patient movement and changes in tumor size and location over the course of treatment. Several companies have established themselves in the Image-Guided Radiotherapy market, developing advanced technologies to improve the precision and effectiveness of radiation therapy. Notable among them are Varian Medical Systems, Elekta AB, and Accuray Incorporated, each providing a range of equipment and software solutions designed for IGRT. General Electric Company, Siemens Healthineers, and Philips also contribute to the market with their imaging devices that are integral to the IGRT process. Show Less Read more
